Group Source Processing of Multiple-Record VSAM Data Sets
Group Source Processing of Multiple-Record VSAM Data Sets
PowerExchange uses group source processing to read bulk data from ESDS, KSDS, or RRDS data sets with multiple record types.
PowerExchange group source processing reads data that is stored in the same physical source in a single pass. By eliminating multiple passes of the source data, group source processing enhances bulk data movement performance and reduces resource consumption on the source system.
To use group source processing, complete the following tasks:
Create a multiple-record data map for the VSAM data source.
Use the ESDS, KSDS, or RRDS access method.
Import the data map into PowerCenter.
